Greatest Common Factor
We found the factors 85,455,987 . The biggest common factor number is the GCF number.
So the greatest common factor 85,455,987 is 1.
Lets's calculate LCM of 713,940,679
Given numbers has no common factors except 1. So, there LCM is their product i.e 455079380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/455079380
Therefore, the GCF of Fractions 85/713,455/940,987/679 is 1/455079380
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 713,940,679 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(713,940,679) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(713,940,679) x common factors =1 x 1 = 1
LCM(713,940,679) = ( 713 × 940 × 679 ) / 1
LCM(713,940,679) = 455079380 / 1
LCM(713,940,679) = 455079380
